Click above for a gallery of the Aptera 2e

The Aptera Forum is buzzing with excitement today as the official set of specifications for the upcoming 2e have been released at the Technology, Entertainment, Design (TED) conference that's taking place right now. Early measurements of the car's very wide front track and comparatively short wheelbase have now been confirmed, along with a weight of just 1,500 pounds and a coefficient of drag of just 0.15, a figure that handily beats even the super aerodynamic GM EV1.

Hard data on the electric drivetrain is also rather intriguing. The electric motor offers up 60 lb-ft of torque at an undetermined RPM and the lithium ion phosphate battery pack has a capacity of 10-13 kWh, leading many to believe that there will be an optional pack capable of extending range from the standard 100 miles up to 125 miles.

Other interesting bits include a standard emergency tire inflation system, interior fabrics and plastics made from recycled materials, a smart key and solar glass. A rear backup camera is optional, as is a DVD-based navigation system. See the complete breakdown after the break. Thanks to Josh for providing the list!

      "Battery output: 10-13 KWh battery pack.
      Range: Up to 100 miles per charge."

      It sounds to me like the 13 kWh pack gets you 100 miles. 130 Wh/mile is still only about half the energy used by our eBox.

      Or would you stick with the 100 Wh/mile, and 3kWh 'range extender' pack option?
        • 6 Years Ago
        Scion xB drag coefficient: 0.32
        • 6 Years Ago
        "Scion xB drag coefficient: 0.32"

        Ha! I would have guessed more like 1.0 ;-)

        But seriously, the eBox also weighs about twice as much, so the 2:1 energy may be about right, but I wouldn't want to guess between 100 and 130 Wh/mile for the Aptera.

        Time will tell I suppose.

      91" wide?! That won't fit in my (European) garage.
        • 6 Years Ago
        Aptera has announced that they're aware of the width issue, and that the release version will be smaller.
      • 6 Years Ago
      So front wheel drive now. So front differential and drive shafts to the wheel pods?

        • 6 Years Ago
        Yup. I'm willing to bet the differential is the stock Azure Dynamics one mentioned on the specs sheet I linked to above.

        And the drive shafts can be seen in recent pictures.

        Probably still not an ideal snow vehicle, because (I find) light vehicles in general tend to have more trouble on snow, but certainly better than the 1 wheel drive version. (I think you mentioned snow driving many moons ago in a post about the Aptera).
        • 6 Years Ago
        Yeah this is a summer vehicle in Canada.

        I find the same thing about lighter vehicles. Even my current ZX2 floats to easily on the snow, and this is with Blizzack WS 50s.
      • 6 Years Ago
      Really like this car but:
      how does it handle the bumpy roads, hell in SF has some really bad streets...
      how does it handle flooding or puddles... or heavy winds and rain, don't want it flying cuz of an 40mph gust blowing at it, though I assume the design will channel it.
      • 6 Years Ago
      Aptera states their weight at 1500 pounds.
      Coincidence that that's the upper Federal limit for motorcycles with 2 or 3 wheels.

      I somewhere read they're over 1900 and on a crash diet.

      Big Problema.
      • 6 Years Ago
      Exactly where are these final specs you speak of - when will this company stop lying and admit it - their initial and final implementation is flawed. If I wanted to buy an electric scooter with a shiny fiberglass shell plopped over it - I would do it myself, and for a lot less that the $45K dollars they will have to charge to get these into production - which mark my words - will never happen !!!!
        • 6 Years Ago
        This is more than just a "an electric scooter with a fiberglass shell", the performance and range ought to tell you that. This was designed from the ground up to be a high efficiency 2 seat commuter car. The market for this type of vehicle might not be huge, but there is a market, and there are already over a thousand deposits for purchase.

        On what basis do you estimate a $45K price? Early estimates indicate a price half that much.
        • 6 Years Ago
        The spec sheet states Lithium Iron Phosphate. Not Lithium ion Phosphate
      • 6 Years Ago
      Who new sperm needed to be as big as a hummer...
      • 6 Years Ago
      That torque figure should be at 0 RPM unless they're stating the less-than-max torque which few manufacturers do.
      • 6 Years Ago
      Its a damn joke, the emperors new clothes 2009! All this talk, I want to meet the geeks that actually have $30,000 to drop...yeah right.
        • 6 Years Ago
        You called?
        • 6 Years Ago
        I've been in line for one of these since the first day they started taking deposits. If I have to drive my 10 year old car another year or two to wait for the Aptera, I'm fine with that.
      • 6 Years Ago
      I'm all for green power as much as the next guy, but I expected a bit more performance out this thing, considering its design. Aptera should not be selling to those green nuts already inclined on buying this; they should be targetting the rest of the world, ala Jeremy Clarkson, as another person stated.
      • 6 Years Ago
      I’m sure this going to be a great BEV that can accelerate, hill climb, cruise and handle the elements on the highway like any modern car.

      Its funny to see people compare one point of motor torque and think they know how peppy it is without any power data.

      One thing I noticed from the video is all the achkermann in the steering. I wonder what the curb to curb is?
      • 6 Years Ago
      I have heard that they use an Azure Dynamics drivetrain, which would mean, based on the 60 #-ft of motor torque (81 N-m), that they are using this system:


      which makes a lot of sense, for a light slippery vehicle.
      Someone with more time than me can work out the acceleration based on the 10:1 drive ratio and an assumed tire diameter.
        • 6 Years Ago
        For comparison the Tesla Roadster:
        torque: 276 ft/lbs
        gear ratio: 8.28:1
        curb weight: 2723lbs
        drag coefficient: .3
        0-60 acceleration: 4 seconds

        Given that the Aptera weights about 1/2 as much and has 1/2 the wind drag(and 3/4 the road drag?) The 60 lb-ft should be enough to deliver acceptable performance with good range from a battery pack. Jeremy Clarkson will be underwhelmed though.
